Slide 12

Key Features • Factory filled and hermetically sealed l eak eak--free in any orientation – quick to install

• Self-contained - no separate power unit no pipes or fittings to install or to leak

• No solenoid or servo-valves simple and reliable

• Motor-Controlled Operation precise positioning and speed speed

• Load -lock on loss of power

check valves hold load indefinitely and safely

• Quiet

no gear train noise

Slide 13

Value Proposition: M-Mac vs HYDRAULIC

• • • • •

Fast & clean installation No leaks & no maintenance Same performance & life Same cost Other advantages: – – – – –

High efficiency / low power draw No solenoid valves No hoses, pipes or fittings fittings No oil contamination of oxidation Factory filled & sealed

Slide 14

Value Proposition: M-Mac vs PNEUMATIC

• Better reliability • Better performance (stiff action and higher force) • Less cost • Other advantages: – – – – –

Lower energy draw No piping No airlines to freeze Internal corrosion/jamming eliminated Less noise

Slide 15

Value Proposition: vs SCREW ACTUATORS

M-Mac

• Twice the force density • Five-to-ten times the life • Same cost • Other advantages: – – – –

Tougher (dirt, moisture, abuse, heat, shock) Higher efficiency / lower power draw Safer (load(load-lock by check valves) Quieter
